.BOBERT TEMPLE, OF PHILADELPHIA, PENNSYLVANIA.

MIXER.

To all {whom it may concern;

Be it known that I, ROBERT M. TEMPLE, a

'citizen of; the United States, residing at my improved mixer.

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and-useful Improvements? in Mixers, of which the following is a specification:

This invention contemplates; certain new and useful lates more particularlyxt'o thathlass of ap paratus employed in mixing bread, cake, and Rings, chocolate," printing ink, paints, and similar masses of a doughy or pasty nature.

The object of the invention is to produce an improved apparatus by means of which the contents of the mixer are subjected to a uniform, though violent agitation, by means of which the dry and liquid materials are first shaken into granular form and subsequently to a smooth and elastic consistency, after which the continuedoperation ofthe apparatus will so completely mix the ingredients within the mixer as to produce a most highly developed uniform mass.

The invention will"be hereinafter fully set forth and particularly pointed out in the claims. F e In the accompanying drawing,:-Figure 1 is a longitudinaL sectional view illustrating Fig. 2 is a transverse sectional view on'the line 22, Fig. 1. Fig. 3 is a side elevation of the beater.

Referring to the drawing, 10 designates a casing or receptacle constructed to receive the ingredients to be mixed, and 11 is a shaft extending longitudinally therethrough, said s'haft being. rotatably mounted in suitable bearings 13. Keyed or otherwise secured to the shaft 11' are end members or spiders 14,

'14, the arms of said spiders being relatively staggered and connected by oppositely inclined diagonally disposed beater bars 16, 17. In this connection it will be noted that one end of eaclnbar 16 is connected to one of the arms of the spider 14 and' extends diagonally toward the shaft'll, being secured to the other spider 14, as shown. Likewise, thearms or bars 17 .extend in 'like manner from the outer ends of the arms of spider 14 to the spider 14. Thus, viewing the beater from the front of the machine, the beater arms 16 are inclined downwardly to the right, and the beater arms 17 are inclined downwardly tothe left. If desired a scraping knife 18 may be secured at its Specification of Letters Patent. Application filed February 27, 1912. Serial No. 680.237.

to one arm-of [each of the spiders 1'4, 14, although it is obvious that for some materials such a :Sfiraper will not be re quired.

The shalt 11 is rotated in any suitable manner, such for instance, through the megears and'pinions 20 actuated bya drive shaft2l, receiving power in any preferred manner. The receptacle .10 maybe dumped by any suitable means, sucheas a segmental rack 22, meshing with a pinion 23, which may be rotated at will by means of a hand wheel 24.

..In ract-ice,.the ingredients to be mixed are p aced within the casing or receptacle 10, and thebeater is rotated by means of the gearing 20. In their rotation the bars 16,-

17, uniformly and violently agitate the said ingredients, first shaking the dry andliquid materials into granular form, and then by continued vibration during the rotation thereof, bringing the mass into a smooth and, elastic consistency. As the rotation of the beater continues the mass is caused to lap over and under from end to end, and from the outside to the inside, so that while said mass is being spun it is also continually changing its position, finally resulting in the formation of a glutinous substance, highly developed and uniform in consistency.

Having thus explained the nature of my invention and described an operative manner of constructing and using the same. although Withoubattempting to set forth all of the forms in which it may be made, or all of the forms of its use, what I claim is 1. An improvement in mixers comprising a heater provided with oppositely disposed end members, and staggered beater bars extending from each member to the other, the contiguous ends of alternate beater bars being located nearer the axis of the beater than the corresponding ends of the remaining heater bars.

2. An-improvenient in mixers comprising a heater rovided with a shaft, end members carried by said shaft, and staggered beater rods extending from each member to the other member, the contiguous ends of alternate heater rods being located nearer to .said shaft than the corresponding ends of the remaining beater bars.

3. An improvement in mixers comprising a heater provided with oppositely disposed spiders provided with relatitely staggered remaining beater bars.

4. An improvement in mixers comprising a beater provided with oppositely disposed spiders having relatively staggered radial arms, and staggered heater bars each extending from the outer end of the alternate radial arms of each spider to the inner portions of the alternate radial arms of the other spider.

5. An improvement in mixers com rising a beater provided with end mem ers, stag ered-beater bars connecting said end mem rs, the contiguous ends of alternate beater bars being located nearer the axis of the beater than the corresponding ends of the remaining beater bars, and a scraping knife also secured to said end members.

6. An improvementin mixers comprising a heater provided with oppositely disposed spiders, said spiders being provided with relatively staggered radial arms, beater bars extending from the outer ends of the radial arms of each of said end members, and a scraping knife secured to one arm of each spider. i

In testimony whereof I have hereunto set niy hand in presence of two subscribing witnesses.
